A real-time anesthesia record keeping system using video

A real-time, Automated Anesthesia Record Keeping (AARK) system was constructed using commercially available video hardware. This system can acquire all of the information that is presented visually to an anesthesiologist directly from monitor screens. The information is recorded on VHS format tape. Use of such a system avoids the need for digital processing while capturing all waveforms, trends, data messages and numerics. Since the data are stored directly to tape, subsequent data analysis can be accomplished. This system can be used with virtually any medical monitor.
